coolant/hose/plenum problem

hey guys my problem is...

the COOLANT hose that goes into the upper plenum wasnt on there tight and it was pouring antifreeze all over the place, i could never see it because it was at night, i just added water, so today i crank it up and im looking its pouring out right under the motor, im like wtf is that so i pop the hood and its spewing out where it connects onto the intake plenum, needless to say i pushed it on there and tightened it and that fixed my leak problem, but if you look theres like puddles of anutifreeze all around my fuel rail and under there in that little valley, i dont know what exactly its doing but its causing rough idle, feels like an engine mount is out when im in the car (at idle only) car drives fine...soon as i stop at a light my cars sounds like its camming or something...

what do you think it is...im gonna try to get a rag and dab all that **** off tomm

i know what that is like

are you referring to the hose that plugs into the neck that sticks out of the front of the lower intake manifold? dont worry about the puddles of coolant, just soak them up with a paper towel. the rest will evaporate. pull those hoses off and make sure they arent chewed up or something. you made need new clamps.

no i am refering to the hose that goes into the UPPER intake plenum, the plenum that actually says 3.8 etc... anyway i checked em and they are good, i was thinking somehow the puddles may have been dripping into my injectors and causing it to burn with the fuel...

i guess not though because the heat evaporated the puddles before ieven had a chance to soak it all up!

if i turn the idle up a tad its ok, im trying to sell this car so how do i turn up the idle, just a screw or something, where is it located?

hmm, im not aware of any coolant hoses that plug into the upper intake. must be an 89-90 3.8 thing.

there is a throttle set screw located on the throttle body right next to the upper right nut that holds the tb to the upper intake.

yeah thats called the "coolant crossover" hose. On 91-97's it goes underneath the intake plenum in a steel tube. If it's leaking then replace the hose or tighten the clamps. Shouldnt be that hard. Id get that problem fixed first then if the idle problem doesnt go away we can address that later.

Reading the codes should reveal what your idle problem is. Could be the IAC. But check the codes and let me know what turns up.
